Gastric pain typically refers to pain in the upper abdomen, and the first step is to confirm whether the pain is indeed caused by gastritis. If an endoscopy confirms gastritis and liver or gallbladder issues are ruled out, there are primarily two causes of gastritis pain: One is the excessive secretion of stomach acid, which irritates the gastric mucosa leading to upper abdominal pain, and can be accompanied by acid reflux, heartburn, and a burning sensation. In such cases, proton pump inhibitors, such as omeprazole, are generally the first choice and can help relieve the pain. Another situation, such as chronic gastritis, combined with exposure to cold or improper diet, can lead to gastric spasms. This often manifests as episodic upper abdominal pain or even colicky pain. Antispasmodic analgesics, such as scopolamine butylbromide, can be appropriately used in these cases, while also ensuring to stay warm and consume a light, easily digestible diet. (Medication should be used under the guidance of a doctor.)
